In my research, I investigate the heating of metallic materials during plastic deformation. While this phenomenon has been known for a long time (for example, continuously hammered iron retains heat for an extended period), gaps remain in its modeling and theoretical understanding. These gaps pertain both to the thermomechanical continuum description and to the connection with the defect structure of a material. Another challenge lies in experimental accessibility, as various studies employing different measurement techniques have yielded partially inconsistent results.

My approach is highly multidisciplinary and multimethodological, aiming to integrate thermomechanical continuum modeling with metallophysical perspectives while actively considering the relationship between theoretical descriptions and experimental observations. Through this, I seek to contribute to a more comprehensive understanding of the phenomenon – one that is both theoretically rigorous and experimentally verifiable.

The experimental method employed is based on in-situ thermographic measurements during deformation experiments, followed by the inverse solution of the heat equation using various approaches to determine heat sources. This knowledge is intended to also provide further insights into the structure of the yield surface in thermomechanical continuum models of metallic materials.
